Hi grim,

A very interesting design that addresses centrigugal force problems associated with most radial moving weight systems. Well worthy of further examination, IMO. Thanks for the extra info.

Do you think this design would continue to self rotate indefinitely provided it was made strong enough to withstand the pounding?

Regards, ovyyus


: : Here is the drawing Grim sent me. Thanks Grim!

: : Now I want to be perfectly clear about this, Grim. Are you saying that this design turned by itself until the parts wore out? Please be honest with us.

: : Thanks,

: : : The drawings you asked to see have been sent to Scott.

: : : Smithy in Australia was able to reproduce this thing from these, by e-mail, so you shouldn't have much trouble.

: : : Beware of flying parts. This is NOT the current design.

: Hi Scott

: It ran until the parts FLEW OFF, not WORE OUT. It BROKE ITSELF. Five to six turns to self-destruction.
: VERY jerky movement, very violent. Why would I not be honest? I could've mentioned this
: a long time ago, but I felt it to not be the "smooth startup" of JB's wheel, as I explained. It's an old
: model dealing with what I tried to say the flaw in unbalanced wheels was, i.e., weights not lifted off the
: bottom perimeter to make a wheel unstable.

: The second-class lever formed by the lever arm and six-ounce weight was assisted by the "helper" spring to raise the weight off the bottom outside stop about 3/4".
: Near the same time, the upper weight became unblocked from the inner stop and tried to "Tarzan" to the perimeter, with the leverage from the six-ounce weight and lever arm
: driving it. The spring at that point slowed the weight's free swing and stored the energy it needed to become the "helper" spring at the bottom, assisting the weight/lever to pull
: the large weight up off the bottom stop at the proper time.

: Regards

: P.S. The drawing you posted was "Modifications", stop pins adjusted and springs lengthened for clearance.
: Smithy in Australia reproduced it and got the same result- Self-Starting Destruction.
